It can be understood that, by arranging the first heat dissipation component 30, the heat generated by the first heat generating device 21 inside the electric control box 10 can be exported to the outside, so that the heat generated by the first heat generating device 21 with larger heat generation amount is prevented from accumulating inside the electric control box 10, so as to effectively improve the internal temperature of the electric control box 10, and improve the working stability and the use safety of the electric control component 100.

The first heat pipe 32 may be configured as a closed annular pipe, or may be configured as a plurality of closed straight pipe sections, etc., the first heat pipe 32 is formed in a low-pressure environment, the first heat pipe 32 is filled with a phase change material, the low-temperature liquid phase change material in the first heat pipe 32 exchanges heat with the first heat generating device 21 in the electric control box 10 and changes into a high-temperature gas state, and the high-temperature gas phase change material in the first heat pipe 32 moves out of the electric control box 10 and exchanges heat with the first heat dissipating member 31.

In this regard, by arranging the first heat dissipation component 30, the embodiment of the utility model can timely export the heat inside the electric control box 10, especially the heat generated by the first heat generating device 21 with larger heat productivity, to the outside of the electric control box 10, so as to effectively reduce the temperature inside the electric control box 10 and improve the working stability and the use safety of the electric control component 100.

Thereby, heat transfer in cooperation with the first heat generating device 21 is achieved by the first heat conductive plate 33.

For example, when the first heat-generating device 21 is provided with a package shell or a package structure, a heat-conducting silicone grease may be further coated between the first heat-conducting plate 33 and the first heat-generating device 21, so as to conduct heat generated by the first heat-generating device 21 out through the first heat-conducting plate 33, and further conduct heat of the first heat-conducting plate 33 to the first heat-dissipating member 31 through the first heat pipe 32, so that efficient heat dissipation is achieved through the first heat-dissipating member 31, the temperature of the first heat-generating device 21 is effectively reduced, and the working stability and reliability of the first heat-generating device 21 are improved.

Therefore, the heat transfer matching efficiency of the first heat pipe 32 and the first heat generating device 21 can be improved through the contact heat exchange between the first heat conducting plate 33 and the first heat generating device 21, so that the heat of the first heat generating device 21 can be more intensively transferred to the first heat pipe 32, the heat of the first heat conducting plate 33 is further conducted to the first heat radiating piece 31 through the first heat pipe 32, the efficient heat radiation is realized through the first heat radiating piece 31, the temperature of the first heat generating device 21 is effectively reduced, and the working stability and reliability of the first heat generating device 21 are improved.

Thereby, the mating heat transfer with the electronic control box 10 is achieved by the second heat conductive plate 43.

Therefore, the heat transfer matching efficiency of the second heat pipe 42 and the second heat generating device 22 can be improved through the contact heat exchange between the second heat conducting plate 43 and the second heat generating device 22, so that the heat of the second heat generating device 22 can be more intensively transferred to the second heat pipe 42, the heat of the second heat conducting plate 43 is further conducted to the second heat radiating piece 41 through the second heat pipe 42, the efficient heat radiation is realized through the second heat radiating piece 41, the temperature of the second heat generating device 22 is effectively reduced, and the working stability and reliability of the second heat generating device 22 are improved.

Specifically, the inductive devices within the electronic control box 10 may be one or more, at least one of which is the first inductive device 221. For example, the inductive device with higher heat productivity may be the first inductive device 221, and the first opening 111 may be disposed at a position corresponding to the first inductive device 221, for example, in some examples, the first inductive device 221 may be connected to a strong current, for example, PFC inductor (where PFC is an abbreviation of Power Factor Correction, power factor correction) or common mode inductor, etc., and the heat dissipation is higher, and the height of the first inductive device 221 is relatively higher, where the distal end (i.e. the end far from the circuit board 23) of the first inductive device 221 is usually the position where the first inductive device 221 is closest to the electronic control box 10, and the first opening 111 is disposed above the first inductive device 221, so that the distance between the distal end of the first inductive device 221 and the electronic control box 10 may be defined as 5mm-10mm in some examples, while improving the heat dissipation efficiency of the heat radiation, and meeting the requirements of safety may also be satisfied.

When the first inductive devices 221 are plural, at least two first inductive devices 221 correspond to the same first opening 111, or each first inductive device 221 corresponds to a different first opening 111, preferably, each first inductive device 221 corresponds to one first opening 111, so that each first inductive device 221 can have a larger heat radiation area, and mutual heat crosstalk between the plural first inductive devices 221 can be reduced.

Similarly, the capacitive devices within the electronic control box 10 may be one or more, at least one of which is the first capacitive device 222. As in some examples, the first capacitive device 222 is a number of capacitive devices that generate relatively large heat among all the capacitive devices, for example, the first capacitive device 222 is a high-voltage power Jie Dianrong that generates relatively large heat, etc., and the first opening 111 is provided corresponding to the first capacitive device 222 so that the first capacitive device 222 may have a large heat-radiating area.

As shown in fig. 2, further, the second heat generating device 22 includes a first inductive device 221, the electronic control box 10 includes a first box wall, the first box wall is located on a side of the second heat generating device 22 away from the circuit board 24, a part of the first box wall protrudes toward a direction away from the circuit board 24 to form a protruding portion 13, an inner side (i.e., a side facing an inside of the electronic control box 10) of the protruding portion 13 forms an avoidance cavity 131, and at least a part of the first inductive device 221 is accommodated in the avoidance cavity 131.

Specifically, the protrusion 13 is provided to form the avoidance cavity 131 to accommodate the first inductive device 221, so that on one hand, the heat radiation area of the first inductive device 221 can be increased, and the heat radiation efficiency can be improved; on the other hand, the protruding portion 13 can cover the heat dissipation of the first inductive device 221, so that the heat flowing to other positions can be reduced to cause adverse heat influence on other components on the circuit board 24, meanwhile, the non-protruding portion of the electronic control box 10 can save materials, and is closer to other components on the circuit board 24, so that heat radiation and heat dissipation of other components are facilitated.

It will be appreciated that the height of the inductive device is relatively high, the distance between the distal end of the inductive device and the circuit board 24 is relatively large, the height of the capacitive device is relatively low, the distance between the capacitive device and the circuit board 24 is small, and the protrusion 13 is provided, so that the distance between the distal ends of the inductive device and the capacitive device and the electronic control box 10 is small by the arrangement of the protrusion 13 under the condition that the inductive device and the capacitive device are ensured to be mounted, thereby being beneficial to heat radiation and heat dissipation of the inductive device and the capacitive device.

In other words, the first box wall is set to be a planar structure, so that the distance between the first box wall and the inductive device is small, and the distance between the first box wall and the capacitive device is large, which is not only unfavorable for the heat radiation and heat dissipation of the capacitive device to the electronic control box 10, but also the heat dissipated by the inductive device can be easily conducted between the capacitive device and the electronic control box 10 to further block the heat dissipation of the capacitive device, and the protrusion 13 is provided in the utility model, so that the heat dissipation efficiency is improved, and meanwhile, the heat channeling between the capacitive device and the inductive device, especially between the first capacitive device 222 and the first inductive device 221, is avoided, and the heat dissipation effect is improved.

Referring to fig. 2, according to some embodiments of the present utility model, the circuit assembly 20 further includes a third heat generating device 23 disposed on the circuit board 24 and located in the electronic control box 10, and the electronic control unit 100 further includes: the third heat dissipation assembly 50 is disposed in the electronic control box 10, and covers one side of the third heat generating device 23 far away from the circuit board 24 to transfer heat with the third heat generating device 23 in a matching manner, and the third heat dissipation assembly 50 includes a plurality of third heat dissipation fins 51 disposed at intervals.

Therefore, the third heat-generating device 23 can exchange heat through the third heat sink 51, the third heat sink 51 absorbs the heat generated by the third heat-generating device 23 and radiates the heat into the internal space of the electronic control box 10, and the electronic control box 10 radiates the heat generated by the third heat-generating device 23 out of the electronic control box 10, so that the heat productivity of the third heat-generating device 23 is reduced.

Illustratively, the heat generation amount of the third heat generating device 23 is smaller than the heat generation amount of the first heat generating device 21.

As shown in fig. 2, the electronic control box 10 includes an inner shell 11 and an outer shell 12 covering the outer shell 11, the inner shell 11 is an insulating shell and is formed with a second opening 112, an end of the third heat dissipation component 50 far away from the circuit board 24 corresponds to the second opening 112, and the outer shell 12 is a metal shell and covers and seals the second opening 112.

Specifically, the first opening 111 and the second opening 112 may be disposed at a spaced apart position, or the first opening 111 may be in communication with the second opening 112, and the distal end of the third heat dissipation assembly 50 may be disposed adjacent to the second opening 112, so that the heat dissipated from the third heat dissipation assembly 50 may be directly radiated to the outer shell 12 through the second opening 112, thereby improving the heat dissipation efficiency.

According to some embodiments of the present utility model, the electronic control box 10 is a closed box body.

Specifically, based on some use environments, such as a humid environment, an oil pollution environment, a dust environment and the like, the electronic control box 10 is arranged to be a closed box body, so that damage to components in the electronic control box 10 due to the influence of environmental factors can be avoided, the electronic control box 10 is arranged to be a closed box body, foreign matters and the like can be prevented from entering the electronic control box 10, and the inductive devices are stored in the electronic control box 10, so that the foreign matters can be prevented from contacting the inductive devices, adverse influence on the inductive devices is avoided, and the working reliability of the inductive devices can be improved.

It should be noted that "closed" as used herein is to be understood in a broad sense, that is, the electrical control box 10 may be understood as closed without a heat dissipation air flow channel (e.g., a heat dissipation hole) or the like.

It should be noted that, the heat dissipation efficiency of the closed environment is low, so that the heat accumulation of the internal environment of the electronic control box 10 is aggravated, the heat dissipation efficiency of the first heat generating device 21 is improved through the first heat dissipation component 30, the heat dissipation efficiency of the electronic control box 10 is improved through the second heat dissipation component 40 outside the electronic control box 10, the heat dissipation efficiency of the second heat generating device 22 and the third heat generating device 23 is increased through the first opening 111 and the second opening 112, and the heat exchange is performed on the third heat generating device 23 through the third heat dissipation component 50 positioned in the electronic control box 10, so that the heat dissipation efficiency and the heat dissipation effect of the electronic control component 100 are effectively improved, the working environment temperature of the electronic control component 100 is reduced, and the use safety and the working reliability of the electronic control component 100 are improved.

In other words, the utility model sets different heat dissipation components aiming at components with different electric powers in the electric control box 10, and has better heat dissipation effect.

Further, it should be noted that the first heat pipe 32 and the second heat pipe 42 of the embodiments of the present utility model may extend along straight line segments and/or curved line segments in the direction of extension.

Therefore, the setting positions of the first heat dissipation element 31 and the second heat dissipation element 41 can be flexibly adjusted to facilitate improving the heat dissipation efficiency of the first heat dissipation element 31 and the second heat dissipation element 41, and the first heat dissipation element 30, the second heat dissipation element 40 and surrounding components can be avoided, or the first heat dissipation element 31 and the second heat dissipation element 32 can be extended to the position with good heat dissipation, for example, in an air duct with ventilation, so that the heat dissipation effect of the first heat dissipation element 30 and the second heat dissipation element 40 is better, and the heat dissipation efficiency is higher.

For example, the electric control component 100 is installed in an air duct of the air conditioner 1000, because of space limitation, the distance between the electric control component 100 and other structural components in the air conditioner 1000 is small, wind resistance of air flow between the structural components and gaps of the electric control component 100 is large, so that air quantity flowing through the surface of the electric control component 100 is small, and heat dissipation of the electric control component 100 is difficult. At this time, when the heat pipe (the first heat pipe 32 and/or the second heat pipe 42) is elongated or bent, the heat dissipation element (the first heat dissipation element 31 and/or the second heat dissipation element 41) at the cold end of the heat pipe may be moved into a position with better ventilation in the air conditioner 1000, so as to improve the heat dissipation effect of the electric control component 100.

For example, the electronic control part 100 is installed in the air duct of the air conditioner 1000, and because of space limitation, the electronic control part 100 is placed close to the compressor or the heat exchanger, so that the temperature of the air flow around the electronic control part 100 is high, and heat dissipation of the electronic control part 100 is difficult. At this time, when the heat pipe (the first heat pipe 32 and/or the second heat pipe 42) is elongated or bent, the heat dissipation element at the cold end of the heat pipe can be transferred to the position with lower air flow temperature in the air conditioner 1000, so as to improve the heat dissipation effect of the electronic control unit 100.

For example, because of the space limitation of the air duct, the electric control part 100 cannot be placed in the air duct of the air conditioner 1000, there is no stable heat dissipation air flow around the electric control part 100, and heat dissipation of the electric control part 100 is difficult. At this time, the heat pipes (the first heat pipe 32 and/or the second heat pipe 42) are elongated or bent, and the heat dissipation member at the cold end of the heat pipe is transferred to the air duct position with stable air flow and lower temperature, so as to improve the heat dissipation effect of the electronic control component 100.

The electric control component 100 can control the compressor 300, the air supply fan 600 and the air exhaust fan 700 at the same time, the electric power of components integrated in the electric control component 100 is higher, the heating value is larger, and based on the use environment requirement of the air conditioner 1000, the embodiment of the utility model can adopt the closed electric control box 10, and when the electric control component 100 of the embodiment of the utility model is applied to the air conditioner 1000, the working temperature of the electric control component 100 can be effectively improved, so that the working stability of the air conditioner 1000 is higher.

Illustratively, the electric control component 100 is disposed in the air exhaust duct, the outlet of the air exhaust duct is communicated with the outdoor side, and the heat generated by the electric control component 100 can be directly exhausted to the outdoor side, so that the heat generated by the electric control component 100 is prevented from flowing to the indoor side under the action of air flow, and the influence on the temperature regulation effect of the air conditioner 1000 is avoided, so as to ensure the temperature regulation stability and reliability of the air conditioner 1000.

The present utility model is not limited to this, and for example, the electronic control unit 100 may be provided outside the housing 200. Note that, the installation position of the blower 600 is not limited, and may be located outside the housing 200 or may be located inside the housing 200; the location of the exhaust fan 700 is not limited, and may be located outside the housing 200 or inside the housing 200, and will not be described here.

Illustratively, the refrigerant within the compressor 300 includes carbon dioxide,
